Saturn is ready for her close-up. This image, taken by the Hubble Space telescope in 2004, offers a stunning view of the planet’s rings. Saturn boasts 9 continuous main rings as well as three fragmentary arcs; they’re made mostly of ice with some dust and rock mixed in. In this image, the main body of the planet casts a dark shadow on the rings.
